Describe SealShare 2.2 on the website

The download page and the admin dashboard screenshots are retaken for
2.2: the demo delivery share now has a download limit, so the download
page shows how many downloads are left and the dashboard shows "3 of 5
downloads" beside the full-width Sort by field. The download limit and
admin dashboard features mention the remaining downloads, the hour a
recipient then has for the files, and the installed version, and the
alt texts match the new screenshots.
